Summary
Medizinische Einrichtungen Bonn uses SAP R/3
Area of Science:
- Health Informatics
- Medical Information Systems
Background:
- The Medizinische Einrichtungen Bonn utilizes SAP R/3's IS-H module for patient administration.
- Seamless data exchange between clinical subsystems is crucial for efficient healthcare operations.
Purpose of the Study:
- To describe the implementation of HL7 2.3 messaging for patient data exchange.
- To evaluate the use of ProtoGen/HL7 for integrating non-HL7 compliant subsystems.
Main Methods:
- Patient data from IS-H proprietary HCM messages are converted to HL7 2.3 messages via a communication server.
- Custom interface applications were developed using the open-source C++ library ProtoGen/HL7 for non-HL7 compliant systems.
Main Results:
- Successful generation of HL7 2.3 messages from SAP IS-H HCM data.
- Development of interface applications enabling data flow to subsystems unable to process HL7 directly.
Conclusions:
- The implemented HL7 messaging system facilitates patient data exchange between clinical subsystems.
- ProtoGen/HL7 provides a viable solution for integrating legacy systems with HL7 standards.
- Ongoing challenges and areas for future improvement in the data integration process are identified.
